To all whom t may concern.'

Be it known that I, LOUIS WILPUTTE', a subject of the King of Great Britain and lreland, residing in the borough of Man? hattan, city, county, and State of vNew York, have invented certain new and useful" Improvements in Coke-0vens, of which the following is a specification.

My invention relates to regenerative coke? ovens, and has for its object, among other things, the construction of ovens andaccompanying parts So as to insure the exact amount of air entering each Hue for combustion with the gas; also to'control the quantity of products of combustion for each regenerator, and to combine the parts comv prismg my oven in the sim lest and most advantageous manner possib e.

ll will now describe my invention withl 3 is a cross-sectional view on a reduced scale,

' the section being taken on theI line 3-3 in Fig. 2; Fig. 4 is a similar view of a portion of the oven, the section being taken on a line v 4-4 in Fig. 2 looking in the direction of the arrow; Fig. 5 is an enlarged longitudinal sectional detail view of a nozzle-brick employed in my device. p

Similar numerals referto similar parts throughout the several gures.

My improved coke-oven comprises a series of chambers 1 which are to contain the material to be transformed into coke, such material being placed in such chambers through openings 2 in the topl thereo or other suitable passages. Between the chambers 1 are located heating chambers or dues 3 separated by partition walls 4 placed in communication with one another at their upper ends by openin s y5. Since the openings 5 of each series o Yheating :tlues 3 are in alinement, they form a continuous passage way 6 for the gases as shown in Fig. 3.

By referring to Fig. 3, it will be seen that my coke-oven as a whole is divided into two communicating parts or sections by means of a wall 7, said two sections being indicated at 8 and 9. Eachl heating due 3 has in communication therewith a regenerating chamber 10, said chambers having placed therein in this instance baliiing pla'tes lll perforated at 12 through which perforations the air or mixed gases may flow, depending upon which series of a1r pipes 13 or 14 shown in Fig. 1 are open.

The air pipes 13 and 14 are connected together by a line pipe 15 which in turn isv connected by a second line pipe 15a to a eachprovided with a valve 17 and 17a respectively, which control the flow of air through the pipes 13 and 14. Air from the blower 16 is forced, either through the pipe 13 or 14 into pipes 18, shown in Fig. 2, located beneath the regenerators 10 and between sa'me, that is to say, there will be one pipe 18 for each pair of regenerators 10. The pipes 18 are connected to the line pipes 13 and 14 by branch pipes 19, shown in' Fig. 1. The ends 20 of the pipes 13 and 14 are preferably sealed. Beneath the regenerators 10 are located the chambers 21, shown in Figs. 2 and 3 which are connected by branch pipes 22 (Fig. 1) to dues 23 leading into a chimney 24. The flues 23 are each provided with a gate valve 215, 25a.

As illustrated in Fig. 2, the pipes 18 in this instance, are located in the channels 26 in the walls 27, and each of said pipes 18 is provided with nipples 28 directed toward the openings 29 ,in the walls 27, as shown in Fig. 3', l"which convey the air, as it passes from the nipples 28, into the regenerators 10.

rlhe size of the openings in the nipples 28 upon the 'pipes 18 may be varied so as l to control the admission of air to each separate generator in accordance with the reqlijirements of combustion, as will be readily understood by those skilled in this art.

Each regenerator 10 is placed in communication with its particular heating flue 3 by a passage 30 arranged in the horizontal table member 31 of the coke-oven proper, as 100 each heating flue 3. Between the gas duct 105 and each port 33 I interpose a removable nozzle 34 which preferably consists of a cylindribal brick somewhat tapered atthe ends and provided with a relatively small opening 35, as shown in Fig. 5, which alines 110 fan or blower 16. 'llhe pipes 13 and 14 are with largeropening or passage 36 in the top. wall of the masonry or brick construe` tion 37 which contains the gas duct 32.

As is shown in Fig. 2, there is an independent gas duct 32 for each set of heating `iues 3, and vby referring to-F ig. 4, it will fbe seen that each gas duct 32 stops short of the partition wall 7, whereby each section of my improved coke-oven is independently heated. By referring again to Fig. 4, it will l'eseenthat there is a se aratenozzle 34 i" for each heating flue 3.

ese nozzles 34 l simply'rest in the recess 38 formed in the coke-oven air will flow through the pipes 13 `sus `top wall 37 for approximately one-half their diameter as shownin Fig. 5, the upper half of the nozzles 34-projecting into a recess 39 in the table member 31. Gas may be conducted to the ducts 32 in any suitable' manner as by pipes 42a for example.

During the Vroperation of my improved and 14 alternately, and the gases will flow through the flues 23 in a correspondingly alternate manner into the chimney 24, according to the wishes of the operator; The usual operation continues, about one-half hour in one direction and then the reverse is employed. In other words, when the material to be coked is placed in the chambers 1 combustion will be produced in section 8 for example, at which time 'air will flow through the pipe 13, the valve 17a in the line 14 being closed, and then gas will be caused to ilow into the ducts 32 in said sec-` tion '8.' The mixture of air and gas will now burn in theheating iiues 3 in said section 8. While .combustion'is taking place'in section 8, the flue 23 'adJacent to section 9 will carry oii' the hot gases to the chimney 24, the gate valve 25HL being closed. The hot gases from section 8 willpass over the partition wall 7 down through the viues 3 and regenerators 10 into section 9 and into the ue 23 adjacentvthereto. The. mixture in section 8 will be allowed to burn for a certain time, say Vone-half hour, as heretofore set forth, at the expiration of which,air will be'shut yofil from pipe 13 and forced into pipe 14 by means of the valves`17 and 17a and 'simultaneously the gate valve 25 will be opened andthe 'gate valve 25 closed. When this has been accomplished, the mixture of air and gas will be burned in secportions of the corresponding nozzles 28, while the distribution among the flues of the same groupof the ases descending therethrough, when the dlrection of ilowthrough the fines is reversed, depends upon the proportions and arrangements of the paths traversed by the streams descending through the flues and is independent of the nozzles 28 by which air is su' plied to these iiues.

The claims of t e present application are restricted to the form of apparatus shown wherein the provision of an individual regenerator for, and connected to each heating flue, with an individual air inlet for each regenerator separate from the waste gas 'outlet connection thereto, is an essential characteristic of the particular means employed to make the distribution of air supplied to the different flues of a group independent of the reverse flow through-the same iiues.

In my co-pending application, Serial No. 7 63,1714, filed April 26th 1913, I have disclosed and have claimed the common features of novelty found in the form of apparatus ydisclosed herein, and other-forms of apparatus in which the distribution of flow in one direction among the different flues of a group is made independent of the'distribution of ow in the oppositev direction through the same flues without the employment -of an individual regenerator for each heating fine. p

The construction of my improved cokeoven, as herein shown and described, is merely for the purposes of illustrating the principle and method of carrying out my invention. In practice it will be formed of brick or other suitable materials and may be somewhat varied from the construction 4.

here shown.

What I claim is f 1. A coke oven structure comprising coking chambers with a plurality4 of heating flues, a plurality of regenerators one indvidual to and connected to one end of each of said fines, said flues bein arranged in sets each comprising a lurahty of iues connected together at t eir ends remote from those to which the regenerators are connected and means for maintaining a flow alternately in opposite directions through said iiues andregenerators comprising outlet connections to the regenerators for conveying waste gas away from the latter, and air supply connectionsV to the regenerators including a separate'air inlet for each regenerator.
